You shouldn't need to defrag a lot but you can also reduce fragmentation other ways:
Create a seperate partition for swap and the temp folder
Get disk partitioning software (you know where to get this)
Move the swap file before moving the temp folder
Set the swap file to a fixed size
Dont use a browser cache
Are they really necessary any more?
In IE set it to as low as possible
In Mozilla set the size to 0kb
In Bittorrent allocate and zero on creation
As soon as you start a DL it created the file and puts zeroes in it
This reduces fragmentation
Azureus can do this. So can many other BT clients
Defrag before you start a big download
I do all of the above. The only things on my system which really end up fragmented are log files which are a couple of kilobytes. These aren't exactly thrashing the disk. You probably know all this anyway but there are people who don't.
